Mating of LVA

The animation archived on this page shows the geocentric phase, libration, position angle of the axis, and apparent diameter of the Moon throughout the year 2017, at hourly intervals.

Radar Mapping Titan

The heavens often seem vast and unchanging as seen from Earth, but movement in the skies is the norm. The relative motions of both Cassini and Enceladus over a 15-minute period create the movement ...

Probe Landing on Titan

The interaction of the solar wind with the Martian moon Phobos creates a complex electrical environment that could impact future exploration.

Astronomy highlights for February 2020: it's the best time of the year to view Mercury; Mars disappears behind the Moon; and the bright red star on Orion’s shoulder, Betelgeuse, has been acting wei...

Soar over the giant asteroid Vesta in 3-D. Put on your 3-D glasses for this ride over asteroid Vesta.

What can you see in the March sky? Jupiter and other planets in the morning, the start of spring with the spring equinox and viewing an open star cluster called the Beehive.

Everyone likes to check the weather in a far away destination before they travel there. This is especially true for spaceflight, where the destination may be where no one has gone before.

Cassini mission leads Earl Maize and Linda Spilker talked about the spacecraft's epic journey and science - and the exciting two-part grand finale.

This is the first footage of one orbiting robotic spacecraft taken by another orbiting robotic spacecraft at Earth's moon. 

Spacecraft Trajectory

These two false-color views from NASA's Cassini spacecraft show detailed patterns that change during one Saturn day within the huge storm in the planet's northern hemisphere.

Final Assembly at the Cape

Rotating asteroids have a tough time sticking to their orbits. Their surfaces heat up during the day and cool down at night, giving off radiation that can act as a sort of mini-thruster.

This animation, from Cassini's navigation team, shows the spacecraft's final orbits in 2016 and 2017. 

What's Up for March? Planet-palooza in the morning, a "Sirius" look at the Dog Star, and an evening trio at the end of the month.

This animation, derived from data obtained by NASA’s Cassini spacecraft, shows how plasma swirling around Saturn is correlated to bursts of radio waves emanating from the planet.

Io in Eclipse

Rosaly Lopes shares how she was inspired to help the exploration of space and how that lead to her role as a planetary scientist.

What can you see in the April sky? The Moon visits Mars in the evening, and later joins Saturn and Jupiter for a spot of tea. Also, how to find Polaris, the North Star.

This is a compilation of the Saturn hexagon movies released on Dec. 5, 2013.

Vesta and Ceres reside in the boundary area of the asteroid belt, where the composition of bodies changes from being almost dry to showing the effects of hydration.

For 13 years the spacecraft’s incredible, truly otherworldly images have revealed the wonder of Saturn in surprising, often awe-inspiring ways.

A simplified model of Jupiter's massive magnetic field, known as a  magnetosphere.
